Contents of the course
Lecture:
- characterization of fatty raw materials: fatty alcohols, fatty acids (IUPAC and INCI nomenclature), esters of fatty acids and glycerol, waxes, unsaponificated lipids from plant source and from crude oil, polyunsaturated essential fats
- preservatives: organic acids and their salts and esters, aldehydes and formaldehyde-releasing preservatives, amines, amides, piridines, benzalconium salts, phenols and derivatives, alcohols and derivatives, parabens, antioxidants, vitamins.
- thickening agents: micelle formation in the present of sodium chloride, polymeric thickeners, biopolymers.
- surface active agents: anionic, cationic, amphoteric, nonionic, soaps and their properties, mechanism of washing, micelle formation, critical micelle concentration, examples of surface active agents.
- fragrances/ compounds with odour: essentials oils, aldehydes, ketones, terpenes, esters, their preparation and purification.
-cosmetic formulations: solutions of compounds, micellar solutions, gels and hydrogels, emulsions (preparation, stabilization, emulsifiers).
- Fundamentals of formulating of simple cosmetics: cleansing preparation and shampoo, emulsion as moisturizing cream.
-skin and hair and their components: conditioning with appropriate chemical compounds (humectants, emollients, protein hydrolyzates, skin barrier, occlusive agents, re-fatting, moisturization).
Practicals:
-characterization of raw materials for cosmetics (melting point, boiling point, refractive index)
